The First Embodiment

Referring to FIG. 1 and FIG. 2, in an embodiment of the present disclosure, an electronic cigarette (not shown) includes an atomizing device 100 and a battery device (not shown) for electrically driving the atomizing device 100. The atomizing device 100 includes a base assembly 10, a liquid storage tube 20, an atomizing core assembly 30 with an atomizing chamber 310 (FIG. 7), an upper cover assembly 40 and a mouthpiece (not shown). The liquid storage tube 20 is sleeved on the base assembly 10, the liquid storage tube 20 and the base assembly 10 form a liquid storage chamber 21 for storing the e-cigarette liquid (as shown in FIG. 7). The atomizing core assembly 30 is received in the liquid storage chamber 21 for atomizing e-cigarette liquid. The upper cover assembly 40 is disposed at one end of the liquid storage tube 20 opposite to the base assembly 10, and is selectively in communication with the atomizing chamber 310 and the liquid storage chamber 21, so as to facilitate the user to inhale the smoke formed after the atomization. When the upper cover assembly 40 is in airflow communication with the atomizing chamber 310. When the upper cover assembly is in airflow communication with the liquid storage chamber 21, the air pressure in the liquid storage chamber 21 can be kept stable, the liquid leakage is prevented, and it's convenient for the user to fill the e-cigarette liquid. The mouthpiece is detachably disposed on the upper cover assembly 40 for the user to inhale the smoke formed after the atomization.

Referring to FIG. 3, specifically, the base assembly 10 is substantially hollow cylindrical, the base assembly 10 includes a base 11 with an inner chamber 110 and an air conditioning ring 13. The base 11 has a substantially hollow cylindrical shape, an air inlet 112 communicating with the inner chamber 110 is defined in a circumferential wall of the base 11. The air distribution ring 13 is circumferentially rotatably sleeved on the outer circumference of the base 11 and has an air conditioning groove 130 in communication with the outside, the air conditioning groove 130 can be in communication with or staggered from the air inlet 112. When the air distribution ring 13 is rotated, the communication area between the air conditioning groove 130 and the air inlet 112 can be adjusted, so that the user can adjust the amount of the air intake as needed.

The liquid storage tube 20 is a hollow sleeve, two ends of the liquid storage tube 20 are throughout. Optionally, the liquid storage tube 20 is a glass tube or a stainless steel tube, which is sleeved outside the base 11, the liquid storage tube 20 and the base 11 together form a liquid storage chamber 21 for storing e-cigarette liquid.

Referring to FIG. 4, the atomizing core assembly 30 is received in the liquid storage chamber 21. The atomizing core assembly 30 includes an atomizing tube 31, a heat generating member (not shown), a liquid guiding member (not shown) and an electrode contact assembly 33. The atomizing tube 31 has openings at the upper and lower ends, an atomizing chamber 310 is formed in the atomizing tube 31. The atomizing tube 31 is provided with a liquid inlet hole 312 communicating between the atomizing chamber 310 and the liquid storage chamber 21. The heat generating member and the liquid guiding member are disposed in the atomizing tube 31 for sucking the e-cigarette liquid in the liquid storage chamber 21 and heating and atomizing the e-cigarette liquid using the electric power from the battery device. The heating element can be a heating wire, the liquid guiding piece can be a liquid guiding cotton; the arrangement of the two can be that the liquid guiding cotton is wrapped around the heating wire, or the heating wire is wound around the liquid guiding member. The electrode contact assembly 33 is disposed at the bottom of the atomizing tube 31, one end is electrically connected to the heat generating member, the other end is electrically connected to the battery device to provide electrical power to the atomizing core assembly 30.

The external air enters the inner chamber 110 of the base 11 from the air conditioning groove 130 of the air distribution ring 13 and the air inlet 112 of the base 11, and then enters the atomizing chamber 310 from the lower end of the atomizing tube 31. The e-cigarette liquid in the atomizing chamber 310 is atomized to form smoke, the external air and the smoke pass through the top of the atomizing tube 31 and the upper cover assembly 40, and then flow into the mouthpiece for the user to inhale.

Referring to FIGS. 5 and 6, the upper cover assembly 40 includes an upper cover 41 and a liquid injecting cover 43 that can move relative to the upper cover 41 between the locking position and the unlocking position. The upper cover 41 is sequentially provided with a smoke outlet 410 and a liquid injecting port 412 along the movement path of the liquid injecting cover 43 from the locking position to the unlocking position, the liquid injecting cover 43 is provided with a through hole 430. When the liquid injecting cover 43 is in the locking position relative to the upper cover 41, the liquid injecting cover 43 is covered on the upper cover 41 and cannot be rotated relative to the upper cover 41, the through hole 430 is in communication with the smoke outlet 410, the liquid injecting port 412 is closed. When the liquid injecting cover 43 is moved from the locking position to the unlocking position with respect to the upper cover 41 by an external force, the liquid injecting cover 43 can be turned over and opened with respect to the upper cover 41, and then the liquid injecting port 412 is exposed.

In this way, when the electronic cigarette is in use, the through hole 430 of the liquid injecting cover 43 is located at the locking position and in communication with the smoke outlet 410, so that the e-cigarette liquid in the atomizing chamber 310 flows out through the through hole 430 for the user to inhale; at this time, the liquid injecting port 412 is closed, and the liquid injecting operation cannot be performed. When the liquid filling operation is required, the through hole 430 is translated from the locking position to the unlocking position by the lateral push, and can be opened by rotating relative to the upper cover 41 to expose the liquid injecting port 412 to ensure the air pressure in the liquid storage chamber 21 is stabilized by pre-relieving, so as to avoid the liquid leakage caused by the change of the air pressure in the liquid storage chamber 21 due to the sudden opening of the liquid injecting cover 43, and the liquid injecting operation can also be performed at the same time.

Specifically, the upper cover 41 includes a bottom cover 414 and a gland 416 disposed above the bottom cover 414. The smoke outlet 410 and the liquid injecting port 412 are sequentially defined on the bottom cover 414 along the moving path of the liquid injecting cover 43 from the locking position to the unlocking position. The bottom cover 414 is disposed at one end of the liquid storage tube 20 away from the base assembly 10, a surface of the bottom cover 414 facing away from the gland 416 is convexly formed with a connection fixing post 4141 having a hollow structure. The connection fixing post 4141 is inserted at an end of the atomizing tube 31 away from the base 11 for fixing the upper cover assembly 40 and the atomizing core assembly 30 to allow the smoke in the atomizing chamber 310 to flow. In addition, the upper cover 41 further includes a sealing ring 418 disposed between the bottom cover 414 and the liquid storage tube 20 for preventing leakage of e-cigarette liquid.

The edge of one side of the gland 416 is recessed inwardly to form a notch 4161 that is open at one end and having a U-shaped structure, both the smoke outlet 410 and the liquid injecting port 412 are received in and exposed in the notch 4161. Specifically, the notch 4161 includes a connecting wall 4162 located at a side of the smoke outlet 410 away from the liquid injecting port 412 and two side walls 4164 connected to opposite ends of the connecting wall 4162 and extending in the same direction. The surface of the connecting wall 4162 near the bottom cover 414 is further recessed to form a recess 4166 in a direction away from the smoke outlet 410, so that a receiving gap having a certain height is formed between the gland 416 and the bottom cover 414. And, the surface of the two side walls 4164 connected to the connecting wall 4162 is recessed in a direction away from the bottom cover 414 to form a translating groove 4165, the translating groove 4165 is in communication with the notch 4161 and the recess 4166. At this time, the two translating grooves 4165 are in communication with the recess 4166 to form a U-shaped groove that surrounds the outside of the notch 4161 and has the same opening direction as the opening of the notch 4161.

One end of the liquid injecting cover 43 is received and confined in the recess 4166 when the liquid injecting cover 43 is in the locking position, and when the end of the liquid injecting cover 43 is moved from the locking position to the unlocking position, the liquid injecting cover 43 can be moved out of the recess 4166 along the translating groove 4165 and turned over. Specifically, the liquid injecting cover 43 includes a cover body 433 and a rotating shaft 431 protruding from opposite sides of one end of the cover body 433. The cover body 433 has a substantially rectangular plate shape, and its shape matches the shape of the notch 4161. The through hole 430 extending through the cover body 433 has a hole wall protruding from the surface of the cover body 433 facing away from the bottom cover 414. When the liquid injecting cover 43 is in the locking position, the rotating shaft 431 is locked in the recess 4166, the hole wall of the through hole 430 abuts against the recess wall of the recess 4166, thereby preventing the gland 416 from being reversed about the rotating shaft 431. When the liquid injecting cover 43 is moved from the locking position to the unlocking position by an external force, referring to FIG. 6, the rotating shaft 431 moves along the translating groove 4165 and moves out of the recess 4166, so that the hole wall of the through hole 430 and the recess walls of the recess 4166 forms a rotational space for the cover body 433 to be turned about the rotating shaft 431 with respect to the upper cover 41. At this time, the upper cover 41 can be opened by inverting the liquid injecting cover 43, so that the liquid injecting port 412 is exposed, the user can perform the liquid injecting operation. The liquid injecting cover 43 can also be relatively closed on the upper cover 41 after the liquid injecting operation is completed, and then pushed back to the locking position from the unlocking position. Throughout the process, the cover body 433 cannot be flipped directly when in the locking position, it is necessary to perform the lateral push to cancel the interference between the cover body 433 and the gland 416, so as to realize flipping of the cover body 433, thus the liquid injecting cover 43 is prevented from being opened during the use of the electronic cigarette, and provides with a child protection function at the same time.

The liquid injecting cover 43 includes a covering portion 432 disposed on the other end of the cover body 433 opposite to the rotating shaft 431. The covering portion 432 extends to both sides with respect to the cover body 433, and has a width in the circumferential direction of the gland 416 greater than the width of the notch 4161. In the specific embodiment, the covering portion 432 has a fan shape that extends toward the both sides of the cover body 433. At the same time, the bottom of the gland 416 on both sides of the notch 4161 is provided with a locking groove 4163 in communication with the notch 4161, the width of the locking groove 4163 in the circumferential direction of the gland 416 is larger than the width of the notch 4161. That is, the locking groove 4163 and the notch 4161 form a stepped groove with a wider upper part and a narrower lower part. Thus, when the liquid injecting cover 43 is pushed into the locking position relative to the upper cover 41, the covering portion 432 is received in the locking groove 4163 and resists the groove wall of the locking groove 4163 to prevent the liquid injecting cover 43 from being pushed in continuously. When the liquid injecting cover 43 is pushed out to the unlocking position relative to the upper cover 41, the covering portion 432 can be removed out of the locking groove 4163 through the opening of the locking groove 4163, so that the liquid injecting cover 43 can be reversed relative to the upper cover 41.

In the embodiment, the liquid injecting port 412 is a circular arc shape surrounding the partial outer circumference of the smoke outlet 410. While matching the shape of the covering portion 432 having a scalloped structure, the size of the liquid injecting port 412 is increased to facilitate the liquid injecting operation.

Further, in order to ensure the tightness between the gland 416 and the liquid injecting cover 43, a sealing groove 4143 is defined in the bottom cover 414 around the smoke outlet 410 and the liquid injecting port 412. The upper cover assembly 40 includes a gasket 45, the gasket 45 is housed in the sealing groove 4143 and sealed around the outer periphery of the smoke outlet 410 and the liquid injecting port 412.

Referring to FIG. 7 together, in the specific embodiment, the upper cover 41 includes a pin 417, the pin 417 passes through the bottom cover 414 from below and is fixed on the gland 416, thus to secure the bottom cover 414 and the gland 416. It is to be understood that in other embodiments, the fixing manner of the gland 416 and the bottom cover 414 can be changed as needed, or the two can be integrally provided, which is not limited herein.

When the liquid injecting cover 43 of the electronic cigarette of the present invention is in the locking position, the liquid injecting cover 43 is covered on the upper cover 41 and cannot be turned over with respect to the upper cover 41, the smoke outlet 410 is in communication with the through hole 430, the liquid injecting port 412 is closed; at this time, the smoking operation can be performed normally and the liquid injecting operation cannot be performed. When the remaining amount of the e-cigarette liquid in the electronic cigarette is insufficient, the liquid injecting cover 43 can be translated from the locking position to the unlocking position to open the liquid injecting cover 43 by turning over to completely expose the liquid injecting port 412 for convenient operation. During the operation, the liquid injecting cover 43 can be turned over after being pushed out relative to the upper cover 41, and cannot be directly turned over. While directly pushing laterally the liquid injecting cover 43, the covering portion 432 is still covering the liquid injecting port 412, that is, the separate turning over or pushing laterally will not expose the liquid injecting port, the infusion port must be opened by a two-step operation with a push in the lateral direction and a turning over, so it can be child proof.
